vide a direct mechanical printing device reproducing telegraphic messages in any ordinary characters. This app aratus is such that it enables the automatic translation of the signals corresponding to the characters and the printing of.

these characters, either on a paper band which is utilized by the operator for the composition of the telegram, or directly on to a page by the use of a cylinder special'signal used to mounted on a carriage and of a cause the type to pass from one line to the following line. This new direct printing device is an entirely mechanical appara tus, compose-d alinos identical pieces so as and to facilitate the t entirely of a plurality of to simplify the manufacture maintenance of the same.

It comprises essentially a selector, sorting and storing up, in accordance with their reception,

the signals correspondingto a character and a printing combining device, receiving the stored up signals from the selector to cause the combining device to come into play in order to print at the moment of printing the corresponding char acter. The selector device form only a single assembly simultaneously. The apparatus can and the printing combining and operate be adapted for the translation of any code whatsoever, notably recorder signals and five element codes synchronously sent out over the telegraphic systems.

The attached drawings show by way of example and not of limita tion one embodiment of the various parts constituting the apparatus, in an adaptation of the invention to the translation of Morse code signals. a In the drawings:

an enlarged scale, a detailed view of a portion of the apparatus.

For the better understanding of the following description it is to be code comprises long signals (dots) of which length of the spacing remembered that the Morse signals (dashes) and short the length, as well as the intervals, are generally adjusted thus: the length of a dot being chosen as a unit period of time,

to three units of the length of a dash is equal time, the length of an interval between signs to one unit of time, the length of an interval between letters to three units of time and the length of five units of time.

the interval between words to the signals in accordby the operation of latches controlling the position of turning bars' and controls the length of the times of operation by the selection of the signals and the length of the spacing periods in or der to release at the appro- I mounted at its centre on an axis 2 and extended upwardly by an extension 3. The armature l is located in the magnetic field formed by preferably laminated pole masses A and 5, set up either by a permanent magnet or by a continuous current passing through a suitable winding not shown on the drawings. The pole pieces are, one of north polarity and the other of south polarity and maintain the armature l stationary either from one side or the other by the passage of the magnetic flux and also upwardly and downwardly. The armature l is moreover subjected to the magnetic field of two bobbins 6 and 1 which receive the line currents. These currents traverse the bobbins sometimes in one direction, sometimes in the other direction, according to whether they correspond to an operative current or to a spacing current. Each inversion of the current in the bobbins 5 and l corresponds to an inversion of the direction of the lines of force of the magnetic field in the armature l which sets up a change of equilibrium in this armature so that it passes from one pole to the other. In the operative or marking position, the armature l is inclined from left to right and in the spacing position it is inclined from right to left. This armature I, by its extension 3 which is carried thereby, drives an escapement plate 8 which is mounted between two slides which allow it to move horizontally, the displacement being produced by the movements of the armature l. marking current received in the bobbins '5 and l of the polarized relay, this plate is displaced towards the left and by a spacing current it is displaced towards the right.

On the one hand, plate 8 in its position of working and spacing connects with two toothed wheels 9 and I driven by the motor of the apparatus which will be described hereinafter, a working or marking selector (hereinafter termed the marking selector) and a spacing selector by their displacement the These marking and spacing selectors, which are identical, comprise racks H and I2 connected by their pivots l3 and M with members I5 and I6 mounted on slides which allow them to move horizontally in the direction of their length, this movement being limited by abutments coming up against their shoulders I! and I8. Return springs l9 and 20 bring back to their initial position the selectors as soon as the racks H or I2 are removed from the toothed wheels 9 or ID by the dis.- placement of the escapement plate 8 and by a which determine lengths of the signals and spaces.

and is always ready to return spring 2]. The members I5 and I6 are shaped at one of their ends in the form of asymmetrical cams and can operate by their movement on feelers 22, 23, 24 and 25. As the moment when the armature I of the relay is inclined in the marking position the marking selector enters into engagement by its rack I I with the toothed wheel 9 and is moved in such a manner that for a dash, which is equivalent to three time units of I5 turns the feeler 22 by its cam. For a dash which is too long, the feeler 23 will in its turn be moved by its cam. A dot which is equivalent to a single unit of time will be without effect on the feelers 22 and 23. When the armature I of the relay is inclined in the spacing position, the spacing selector enters into engagement by its rack I2, with the toothed wheel I8 and is displaced in such a manner that for a space between letters which is equivalent to three units of time, the selector I6 turns the feeler 25 by its cam. For a space between words, which is equivalent to five units of time, the feeler 24 is operated in its turn. A space between signs which is equivalent to a single unit of time is without effect on the feelers 24 and 25.

On the other hand, this escapement plate 8 controls the movement of a rotary cam 28, hereinafter called the selection cam, .and allows it to make a half turn at the beginning and a half turn at the end of each sign received. To this end the cam 28 as well as the trigger piece 29 is mounted, on a shaft 39 driven by the motor through the intermediary of a friction coupling turn in a clockwise direction, it being retained however at each half turn by the plate 8 which arrests the movement of the trigger 29.

The coupling driving the shaft 30, which is not shown on the drawings with the object of simplifying the same, simply consists of a driven plate connected to shaft 30 mounted between two driving plates- An electric motor is coupled to a main driving shaft 3I which is turned at the rate of one turn for four time units of the Morse code and on which is pinned a pinion 32, which pinion, through the intermediary of a large wheel, not shown on the drawings to simplify the same, drives a pinion connected with the driving plates of the coupling driving the shaft 38 in such a manner that this shaft makes one half turn during the length of a single time unit. The large wheel situated between the main driving shaft 3! and. the shaft 39 drives through the intermediary of angle gears and helicoidal gears, friction couplings not shown, mounted on the shafts 33 and 3 3 of the toothed wheels 9 and I0. These friction couplings are provided withtheobject of enabling the driving motor to continue. to turn when, for a prolonged marking or spacing current, the racks II or I2 driven by the toothed wheels 9 or I9 arrive at the end of their movement and are stopped by their abutments which thus have the effect of causing the friction coupling to slip. Also, the friction coupling driving the shaft 38 of the cam 28 slips. each time the trigger 29 is stopped in its movement by the plate 8.

In order that the cam 28 and the trigger 29 may be clearly seen on the drawings, the armature I of the relay is shown in its marking position and the two members 28 and 29 are shown in the like position. In order to return these members to the spacing position, in which position all the other parts of the apparatus are the Morse code, the selector shown, the armature I of the relay must be inclined to the right which causes the displacement towards the right of the escapement plate 8 as well as the racks I I and I2. The trigger 29 instead of abutting on the right hand part of the escapement plate would then abut on the left hand part of the same. The projection on the cam 28 instead of being turned upwardly would be turned downwardly.

The selection cam '28 unlatched through the intermediary of the trigger 29 by the escapement plate 8, as hereinbefore described, operates a striker 35 which, for each sign received, unlatches in its turn the latch of the turning bar corresponding to this sign. To this end, the cam 28 operates, during its first half turn, on the passage of the relay and of the plate 8 from the spacing to the marking position, on a lever 36 mounted on a horizontal axis 31, which lever, by its upper part, pushes a pawl 38 pivoted at 39 and, by its lower part, draws a rod 48 pivoted at M and, during the second half turn of the cam 28 upon the movement of the relay and of the plate 8 from the marking to the spacing position, the said cam 28 operates the striker 35 by means of an outstanding lever 42 mounted on the horizontal axis 3?, operating a bell crank lever 48, pivoted at 44, supporting a rod 45 on which the striker 35 slides, which striker, by reason of its movement from left to right, strikes and unlatches one of the latches 46 mounted on the same rod 41 and kept cooked by the springs 8 mounted on the rods 49.

The latches number thirteen and form six groups of two latches plus a single latch. In order to simplify the drawings, only a single group of latches has been shown. In each group the first is a latch operated by a dot 46a 48b 46c etc. and the second is a latch operated by a dash 46a 46b 46c etc. The thirteenth latch 45g is operated in the case of trouble as will be explained hereinafter. The striker which must be capable of moving in front of the latches and of occupying for this purpose seven successive positions is guided by a vertical slot provided in the rack 58.

This rack, supported by two horizontal slides, is moved tooth by tooth, by the pawl 38 controlled by the cam 23, at each of its movements from spacing to marking and is maintained in its successive positions by a retaining pawl 5I pivoted on a shaft 52 from which it is independent. A spring 53 sets the pawls 38 and M and a spring 54 returns the rack to its initial position, with one tooth of the rack in advance of the first group of latches as soon as, the combination having been registered by the combining device, as will hereinafter be explained, a lever 55 controlled through the shaft 52 by the lever 55 has disengaged the pawls 38 and 5| from the rack. At each of its seven positions the striker can operate either a dot latch or a dash latch. It follows for this purpose a horizontal groove which is provided in a guide 5'! in the form of a T, the lower part of which is pivoted at 58 on a controlling member 59 called the switching arm, which is mounted on an axle 60, and, at each new sign, is placed in a position enabling the striker to register a dot, by the rod 49 operated at each first half turn of the cam 28.

When the sign received is a dot, the striker 35 unlatches on the second half turn of the cam 28 the dot latch of the group corresponding to the sign received before which it has been positioned by the rack 59; the first group, springs 94 mounted on the rods 95. These turnif'it should-be the first sign, the second group ing bars at the'moment of their'movement toif it should bc second sign etc. Wards the right, produced by the thrust of the When the received sign is a dash, the above cam 15 on the levers 85 and 90 which control described operation takes place in the same way them are some in the spacing position and others 5 '22 which by its shaft iii, a lever 92 and a rod or has not been unlatched by the striker 35 at e3, pivoted at 64, rocks the switching arm 59 the moment of the selection of the signals form which raises the guide 51 and places the striker ing the combination which they are about to sign received, in front of which it has been 96g, mounted side by side on the same horietc. or spacing, which the thirteen turning bars 93 thus be red p by he successive unla hi bining discs is operated by the turning bar which v y e dash The three d ts Wi l hav ing bars 93 either at their lower part or at their been stored up in their order of arrival by the upper part, according t Whether the turning bars upper end an axle 92.

The discs of the combining device maintained cocked against the latches 46 by are surrounded by fifty one type bars which are 1 combining device all identical and correspond to the characters of the code. Each type bar at one extremity gears with a character carrying lever I05 capable of pivoting on an axis I01 and maintained in en gagement with it by a spacing piece not shown on the'drawings. The fifty one character carrying levers I06 are identical and support the typographical characters I08 which are terminated by a slightly conical part engaging in a like coniis hooked a spring I09 which tends at all times to return the character carrying lever against its type bar and to press the type bar I05 against the discs 96 of the combining device. A type disc IIO which maintains in its initial position all the type bars I05 clear of the discs 96 of the combining device, slides along the main axis of the by means of a lever I I I mounted on a pivot I I2 which is connected to it by a the face of the cam 16.

At the beginning of the rotation of the cam 16 the type disc II9 does not move in order that the turning bars 93 may transmit the stored up combination to the discs 96 of the combining device. As soon as the combining device has received the combination the type disc H0, due to the shape of the H4 and the fifty combining device.

sponding to the set ing the longitudinal cam 16, is moved by the spring one type bars fall against the Only that type bar correup combination encounterslot formed by the thirteen to the type disc; the other combining discs are not caught up by this type disc. At this moment the cam- 16 presents a hollow under the roller H5 and the pull of the spring produces a movement of the type bar hooked on to the disc .I I which projects the corresponding type character against a band of paper passing over the roller I I1 which produces the impression of the character. During the last part of its turn the cam 16 returns the type disc to its initial position in order to move the type barsaway from the combining device and to retighten the spring I I4. The spring I09: of the type bar which comes into play also returns its character carrying lever to its initial position against this type bar. An adjustable abutment II8 enables, by limiting the movement of the type disc I I0, the typing to be regulated at will, this being due solely to the tension of the spring I I4 and is independent of the speed of the cam shaft 13 and hence of the speed of reception. Inking is assured by means of an inked ribbon passing before the band of paper and which is, as in writing machines, supported by appropriate spools.

The thirteenth disc 96g of the combining device, which has already been referred to, corresponds tothe thirteenth latch 46;; which has also been mentioned, and functions in the case of trouble, to prevent the typing of an erroneous character, by blocking all the slots which might have been formed in the first twelve discs and by forming a slot in which there engages at the moment of the impression a type bar controlling the typing of'the signal not understood. To .this end the latch 46g which controls the disc 96g of the combining device is unlatched in either of two ways,

the latch 469 in the same manner as the striker 35.

The printing cylinder II1 which drives the paper band on I2I is A latch I32 on which the other side of the shoulder presses keeps this abutment in such a position that the pawl I2I can at each operation only drive the ratchet wheel I20 one tooth. At the moment of typing through the intermediary of a return lever I33 mounted on an axle i34 operated by I36, the pusher I30 acts on the control lever I21 and sets the pawl I 2I which drives the ratchet wheel I20 one tooth as soon as the impression of the character has taken place. This advance of the paper band produced tooth by tooth on the ratchet Wheel I20 by the pawl IZI corresponds to the spacing of two consecutive characters.

by the spacing selector I6, of an interval between words, the feeler 24 turned by the cam of this selector I frees the abutment I29 by disengagement of the latch I32, through the intermediary of the shaft I31 and a lever I38 on which is pivoted at I39 the latch I32 in order to prepare for a double regulated and rheostat will enable the speed of the motor to be a scale graduated in words per minute, mounted on the motor, renders this adjustment particularly easy.

In the preceding description the rack 50 must return to its initial position in a very short time which corresponds to the time between the selection of an interval and the beginning of the following sign, which can present considerable disadvantages at a high speed.

In order to overcome this state of affairs, the

' modification shown in Figure 3 may be employed.

only the points :Fig. 3 shows, on an enlarged scale, a detailed view of the improved mechanism by means of which the pawls 38 and 5| are disengaged from the rack 50 Ihere is thus obtained, as will. hereinafter be explained, a much longer time within which the rack 5|] can return to its initial position. i

For the sake of clearness, the pawls 38 and 5| have not been shown completely in Figure 3, but

, its position of ed, including a In the modification in question, the rack 5|], instead of coming to rest in a position in which one tooth of the same is in advance of its first marking or working position, returns actually to its first marking or working position, which is rest, so that for the first sign it is not displaced, which provides for the return of the rack to its position of rest, in addition to the time between the selection of an interval and the beginning of the following sign, all the time of the passage of this sign, together with a part of the interval-which follows this sign. To this effect, a pawl M0 pivoted at ii and controlled by a spring 32 (Figure 3) maintains'the lever 55 in the upper position through the medium of a notch 55a provided on this member, this being the position in which the rack 50 is disengaged from its pawls 38 and 5 as soon as the cam shaft has operated it due to an interval between words. The rack 5Q, disengaged from the pawls 5| and 38, returns to its first working position which is its position of rest and is all ready for the first sign.

On the arrival of this first sign, the pawl 38 is operated without displacing the rack since it is disengaged therefrom.

In its displacement this pawl forward end 38a (Fig. 3) the pawl Hi0 which by reason of this movement frees the lever 55 and allows the pawl 38 and 5| to fall on to the rack.

38 pushes by its 50 by one tooth and the above described operation will take place.

The control of the lever 55 is in this case effected by a simple pusher (not shown) in such a manner as not to interfere due to its engagement therewith with the return of the levers HM and What I claim is:- Y
